Introduction. Rupture of an unscarred uterus is extremely rare and associated with severe maternal and fetal morbidity. Risk factors are second-stage dystocia, grand multiparity, high parity, labor induction or augmentation with oxytocin or prostaglandins, delivery after the 42nd week of gestation, neglected labor, fetal malpresentation, breech extraction, and instrumental delivery. Case Report. A 44-year-old multipara (gravid3 para3) underwent induction of labour at 40 + 3 weeks of gestation. The patient?s medical history showed no uterine surgeries, but her first delivery was instrumental, with vacuum extractor. The induction of labour was initiated by oxytocin infusion of 6 mIU/min. Continuous fetal heart rate monitoring was performed and there were no signs of fetal distress. Fetal descent in the second stage of labor lasted an hour, which is slightly over than average duration for multiparas. A live female infant weighing 3380 g was born and the pediatrician started resuscitation of the baby. Apgar score was 1/3/3. Ten days following the delivery, the patient was admitted to Emergency Gynaecology Department of the Clinic of Gynecology and Obstetrics due to abdominal pain, left sided retrouterine hematoma, and foulsmelling vaginal discharge. Laparotomy was indicated due to suspected uterine rupture. The intraoperative findings showed subinvolution of the uterus with signs of panmetritis and on the left side below the round ligament there was a 2 cm long rupture, passing through and invading the lateral and posterior walls of the uterus. A total abdominal hysterectomy with bilateral salpingo-oophorectomy on the left side was performed. Conclusion. Although a reliable prediction and prevention do not exist, the obstetricians? awareness of this rare event in unscarred uterus may decrease maternal and neonatal morbidity. This case report is an example of a serious and difficult outcome after a seemingly low-risk situation.

Introduction. Extensive use of assisted reproduction has resulted in an increased incidence of triplet pregnancies, which are associated with higher risk of complications in mothers and newborns. Material and Methods. A retrospective study reviewed a total of 85 triplet pregnancies delivered at the Department of Obstetrics and Gynecology, Clinical Center of Vojvodina, Novi Sad, from January 1, 2010 to December 31, 2017. Results. The average maternal age was 32 years and the average body mass index was 30.56 kg/m2. The average gestational age at birth was 32 weeks. One patient (1.18%) had vaginal delivery, while 84 (98.82%) pregnancies were completed by cesarean section. The average blood loss was 1294 ml and there was one postpartum hysterectomy. The most common maternal pregnancy-induced complications were sideropenic anemia (70.58%), hypertensive syndrome (40%) and obstetric cholestasis (35.29%). Preterm premature rupture of membranes was observed in 17 (20%) patients. Prophylactic cerclage was performed in 57 patients (67.05%) and 12 patients (14.11%) received tocolytic therapy. The average birth weight of the first newborn was 1838 g, 1755 g of the second, and 1695 g of the third. Body weight ? 1500 g was observed in 61 newborns (24.01%). The mean Apgar score in the first minute was 7, while in the fifth minute it was 8. Respiratory distress syndrome was found in 64 newborns (25.19%). Conclusion. Monitoring and treatment of triplet pregnancies remains a complex task for obstetricians due to the increased incidence of prematurity and perinatal morbidity.
